STPS40100CT Equivalent & Substitute Parts

Part Overview

The STPS40100CT is a Schottky diode array manufactured by STMicroelectronics, configured as a 1 Pair Common Cathode arrangement rated for 100 V DC reverse voltage and 20 A average rectified current per diode. The device is packaged in a Through Hole TO-220-3 configuration and features fast recovery characteristics (≤ 500ns, > 200mA Io).

The STPS40100CT is classified as Obsolete. Identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production builds, repairs, and field replacements where the original part is no longer readily procurable from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS40100CT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3

Performance Parameters:

• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Compliance Parameters:

• RoHS3 Compliant

The MBR40100CT from SMC Diode Solutions satisfies all mandatory matching parameters and performance criteria, establishing it as a direct substitute for the STPS40100CT. Both devices share identical diode configuration, Schottky technology, 100 V reverse voltage rating, Through Hole mounting, and TO-220-3 package specification. Both devices maintain fast recovery speed characteristics and ROHS3 compliance.

Engineering Selection Recommendations

Primary Substitute: MBR40100CT

The MBR40100CT is the direct substitute for the STPS40100CT. Selection of the MBR40100CT is based on the following engineering criteria:

1. Functional Equivalence: Both devices are 1 Pair Common Cathode Schottky diode arrays with identical 100 V reverse voltage rating and TO-220-3 package specification.

2. Performance Compatibility: Both devices meet fast recovery speed requirements (≤ 500ns, > 200mA Io), ensuring equivalent switching performance in rectification and protection applications.

3. Compliance Status: The MBR40100CT maintains ROHS3 compliance, matching the regulatory status of the original part.

4. Product Availability: The MBR40100CT is classified as Active, ensuring continued availability and supply chain stability compared to the Obsolete status of the STPS40100CT.

5. Packaging Consistency: Both devices utilize identical Through Hole mounting and TO-220-3 package configuration, permitting direct board-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the MBR40100CT be used as a direct replacement for the STPS40100CT in existing designs?

A: Yes. The MBR40100CT is a direct substitute. Both devices share identical diode configuration (1 Pair Common Cathode), Schottky technology, 100 V reverse voltage rating, fast recovery speed characteristics, and TO-220-3 package specification. No circuit modification or board redesign is required.

Q: Are there any differences in the package specifications between these parts?

A: Both the STPS40100CT and MBR40100CT utilize the TO-220-3 package for Through Hole mounting. The MBR40100CT is supplied in Tube packaging, while the original part packaging is not specified. This difference affects only procurement and handling; the component package itself is identical.

Q: What is the significance of the Obsolete status of the STPS40100CT?

A: Obsolete status indicates that the STPS40100CT is no longer manufactured or actively distributed by STMicroelectronics. The MBR40100CT, classified as Active, is currently manufactured and available through distribution channels, making it the appropriate choice for new designs and ongoing production requirements.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the STPS40100CT and MBR40100CT are ROHS3 compliant. Both parts carry the same HTSUS classification (8541.10.0080) and EAR99 ECCN designation.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in diode configuration, Schottky technology, 100 V reverse voltage rating, fast recovery speed (≤ 500ns, > 200mA Io), Through Hole mounting type, and TO-220-3 package specification. These parameters ensure functional and mechanical compatibility in the application circuit.
